Fyi E85 can be anywhere from 50% to 85%. They need more gasoline in the winter or you have starting issues in cold weather. So you may have issues if you tune on summer blend and get a tank of winter blend. EFI copes better because the O2 compensates. Rumer has it that even during the summer, there is a lot of variability.
